REVERSIBLE-DISK PLOW- SPEGIFIGATION forming part of Letters Patent N0.778,838, dated January 3, 1905.

Application filed June 29,1904. Serial No. 214,659.

To all whom it may concern-.-

Be it known that I, ROBERT C. BELK, a citi- Zen of the United States,residing at Mount Holly, in the county of Gaston and State of NorthOarolina,have invented a new and useful Reversible-Disk Plow, of whichthe following is a specification.

This invention relates to plows, and especially to disk plows, and ithas particular reference to single-disk plows which are directed by theoperator walking behind the plows, the object of the invention being tofacilitate the turning of the disk at the end of each row in order thatthe sod may be turned in the desired direction.

Theinvention consists in improved supporting means for the shaft uponwhich the disk plow is mounted.

The invention further consists in improved means, in the nature of anadjustable landside, to assist in supporting the plow-disk at thedesired adjustment.

With these and other ends in view the invention further consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

The accompanying drawings illustrate simple and preferred forms of theinvention, it being, however, understood that no limitation isnecessarily made to the precise structural details therein exhibited,the right being reserved to any changes, alterations, and modificationsto which recourse may be had without departing from the spirit orsacrificing the advantages of the same.

In said drawings, Figure 1 is a perspective view of a walkingdisk plowconstructed in accordance with the principles of the invention. Fig. 2is a perspective view illustrating modified means for reversing thedisk-carrying shaft. Fig. 3 is a detail plan view showing the landside,the disk, and related parts.

Corresponding parts in the several figures are indicated by similarcharacters of reference.

In carrying out the invention a plow-beam 1 is provided, having avertical perforation 2 for the passage of a stem or shaft 3, carryingmeans, such as a collar 8 upon the stem 3, may

be employed to retain said stem or shaft at the desired elevation. Thefront end of the bracket 6 is provided with a downwardly-extending foot9, with the lower end of which are connected rearwardly-diverging blades10 10, which converge at the front to form a cutting edge 11. The blades10 are provided near their rear ends with inwardly-extending bolts orthreaded members 12, connected by a turnbuckle 13, whereby the saidblades may be spaced at various distances apart at their rear ends. 10is afforded by resilient arms or members 14, which connect-said bladeswith the rear portion of the brackets 6.

For the purpose of adjusting the plow-disk and retaining it at variousadjustments several means may be resorted to, two of which have beenillustrated, respectively, in Figs. 1 and 2 of the drawings. In Fig. 1there is connected pivotally with the said plow-beam a segmental rack15, the teeth of which are beveled to mesh with the teeth of abevel-pinion 16, secured upon the stem or shaft 3 above the plow-beam.The segment-rack 15 has a downwardly-extending arm 17 which isconnected, by means of a suitably-supported sliding rod 18, with anoperating-lever 19, having a spring-actuated dog or pawl 20 adapted toengage a segment-rack 21, whereby the parts may be retained at anydesired adjustment. It is obvious that by manipulating the lever 18 therack-segment 15 may be operated to turn the pinion connected with thestem or shaft 3, thereby turning the latter in its bearings, causing thedisk to turn the furrow-slice either to the right or to the left, as maybe required. The blades 10 10 being adjustable by means of theturnbuckle 13, it is obvious that the plow-disk 4: may be placed'atvarious angles to turn a furrow-slice of any desired Additional supportfor said blades width, the blades 10, which constitute scrapers, beingadjusted and properly spaced apart at their rear ends, so as to squarethe bottom of the furrow. The plow will be supported in any desiredposition by means of the dog or pawl upon the lever 19 engaging therack-segment 21.

Under the modification illustrated in Fig. 2 the stem or shaft 3 isprovided at its upper end with a cross-bar 22, extending slightly beyondthe sides of the plow-beam, the ends of said cross-bar being connecteddirectly by means of rods 23 with a pair of levers 24:, one of which ispivoted to each side of the beam. Secured upon the upper side of thelatter is a rack 25, provided on each side thereof with rearwardlyfacingteeth 26, which said teeth extend beyond the sides of the beamsufliciently to be engaged by the levers 2 1, which possess sufficientresiliency to spring readily into engagement with the said teeth. Inorder to shift the position of the plow-disk, it is only necessary todisengage the lever 24, which at the time is in engagement with one ofthe rearmost teeth 26 at one side of the beam. Said lever is thencarried forward, it being meanwhile held out of engagement with theteeth, thus pushing upon one end or arm of the cross-piece 22 andcausing the plow-carrying stem to turn upon its axis, the opposite lever24 meanwhile sliding over rearwardlyinclined teeth 26, constituting acatch which prevents reverse movement after the desired point ofadjustment has been attained. It will thus be seen that while twooperatinglevers are provided only one of said levers is required to beoperated in order to cause the desired adjustment to be effected.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood.

By the construction of the bracket herein described a secure bearing isprovided for the disk-carrying stem or shaft.

The various adjustments of which the plow is capable will enable it tooperate successfully in soil of various kinds and conditions, making thefurrows as deep and wide as circumstances will permit.

Having thus described the invention, what is claimed is 1. In areversible-disk plow, a beam having a perforation, a bracket connectedwith said beam and having a bearing in alinement with said perforation,a disk-carrying beam journaled in said bracket and perforation, a footextending downwardly from the bracket, rearwardly-diverging bladessecured to said foot, and means for adjusting the disk-carrying stem.

2. In a reversible-disk plow, a plow-beam, a bracket secured to theunder side of said beam and having a bearing, a disk-carrying stemjournaled in said bearing, a foot extending inwardly from thescraper-blades near the rear 7 ends of the latter, a turnbuckleconnecting said threaded members for the adjustment of thescraper-blades, and means for axially rotating the disk-carrying stem.

4:. In a device of thesclass described, a plowbeam, a bracket secured tothe under side of said beam and terminating in a bearing at its frontend, a disk-carrying shaft journaled in said bearing, a foot dependingfrom the bracket, scraper-blades connected with said foot and divergingrearwardly, means for adjustably connecting and spacing apart the rearends of said scraper-blades and resilient arms connecting the latterwith the bracket upon the under side of the plow-beam.
